Yes! I thought I had gremlins in my car when as I made a turn my radio suddenly turned on

It didn't take long to find out I was hitting the Mode (i.e. ON) button. I've done this numerous times but I seem to be getting used to it a little. But yes, there's not enough room between the wheel and the buttons for much finger movement!
I'm not aware of any way to disable them though. I'd recommend giving it a little more time to see if you can adjust your motor memory for this new vehicle..
